How to Fix WhatsApp Not Scanning QR Code

To use WhatsApp on the Web or on the Browser on the PC app you need to scan to QR code so your Whatsapp account gets linked to the device in which you want to use it along with the Whatsapp app on your phone.

Most of the time dust gets accumulated on the screen or on the camera which prevents the proper scanning of the QR code.

If your screen and camera are clear of the dust and still you are not able to scan the QR code and link the account, then you are at the right place.

In this guide, I will tell you, How you can fix Whatsapp not scanning the QR code issue.

How to fix WhatsApp not scanning the QR code issue

1. Scan the WhatsApp QR code with the WhatsApp scanner only

It may sound silly, but some users may try to scan the WhatsApp QR code scanner with the Camera App or with another. It is not their fault as many QR codes can be scanned by Camera only they don’t need any specific App to get scanned.

But some scanner needs to be end-to-end encrypted so they can only be scanned by the particular app in which they are getting used. So scan the WhatsApp QR code scanner with WhatsApp on your only.

2. Clean any dust particles from the camera and the scanner screen

Before scanning the QR code you need to make sure that both the Camera and the Screen are free from dust particles. As any dust particle on the Screen will hinder the QR codes and any dust particle on the Camera will not let the scanner get scanned properly.

So clean both with a soft cloth and see if the QR code is getting scanned or not.

3. Check if the Whatsapp server may have a problem

The issue could be with the WhatsApp web servers as seen in recent times when many users reported their WhatsApp is not sending messages or downloading any media. The same could happen with the WhatsApp Web servers too.

Visit the IsItDownRightNow website and check if users have reported any issues or outages.

If WhatsApp Web is experiencing a technical issue, wait until the issue is resolved from the Whatsapp end. In between you can also ask your friend if their WhatsApp is working to rule out the possibility of the problem from your end. If the problem is from your end try other fixes.

4. Check your Internet connection

When linking your WhatsApp to a new device, both the WhatsApp mobile app and the WhatsApp Web require an active internet connection. If any of the devices are not connected to the internet or if the connection is weak, you may face an error while scanning or the scanner will not appear altogether.

Hence you need to make sure that both of your devices are connected to the internet.

Or if the internet is not working properly then follow the instruction on how to fix your internet connection from here.

After setting up your internet connection follow the other fixes.

5. Change the Network connection on both devices

If you have made sure that your internet connection is now working properly even then you are not able to link your device then this could be due to an issue with the ISPs(Internet Service providers).

Hence try connecting both your Phone and the Browser machine to another Wi-Fi or internet connection and try to connect the devices.

6. Close both Whatsapp Web and WhatsApp Mobile and Start Again

Restarting something is always the best idea if something is not working. The same goes for this issue.

Restarting any program or device clears out any unworkable permission and gives that program or device a fresh start.

Hence Close WhatsApp on your Phone and start again. Also, close the browser and start it again. Search for the and scan the code again.

7. Log out from All the Connected Devices

If you have previously linked any devices to your Whatsapp then this problem may arise. So we suggest you first remove any previously linked devices from your phone and then add the new one. Follow the given below steps to remove linked devices from your phone:

1. Open Whatsapp on your phone by searching from the list of apps.

2. Whan the app is opened Tap on the three vertical dots in the top-right corner (or tap on Settings if you use an iPhone)

3. When the menu appears click on the Linked devices.

4. From the list of the linked devices tap on the device or browser you want to disconnect from.

5. Tap on LOG OUT and the devices will be unlinked from your WhatsApp account.

After removing the linked device from your Phone connect the device by scanning the QR code to which you wish to connect.

8. Clear Browser and WhatsApp Mobile App Cache

Cache stores temporary information about the website which you visit to make it load faster the next time you visit. The same happens with the mobile App cache. But sometimes corrupted files in the cache can cause issues with the normal functioning of both the browser and app. So it is recommended in this fix to clear Browser and WhatsApp Mobiel app cache. Here is how you can do that:

Clear Cookies in Chrome for Desktop

1. Click on the three dots at the top-right corner, select More Tools, and then click on Clear Browsing Data.

2. Choose the time range from the box at the top, tick only Cached images and files, and then click on Clear data at the bottom.

Clear Cookies in Chrome for Mobile

1. Open Chrome, tap the three dots at the top-right corner, and select History.

2. Tap on Clear Browsing data at the top.

3. Select a time range from the drop-down menu at the top, tick Cookies and site data, and tap Clear data at the bottom.

4. Click on the Reset Now button to confirm and restart your computer.

After resetting all the network settings try scanning the QR code and see if it works or not.

10. Disable Hardware Acceleration

Turning off hardware acceleration in your browser may also resolve the issue. The hardware acceleration feature offloads tasks to your device’s specialized hardware, such as GPUs, instead of consuming CPU resources. While enabling this feature improves the browser’s performance, it can sometimes backfire and cause the app to not work properly.

Due to this reason if this feature is turned on your browser then turn it off. Follow these steps to disable it in Chrome:

1. On the top-right corner click on the three dots and then on Settings.

2. When the settings page opens up click on the System on the left pane.

3. Turn off the toggle button next to Use hardware acceleration when available.

After doing this try to open the WhatsApp web and scan the QR code.

11. Disable Browser Extensions

Although extensions do not hinder any working but sometimes depending on the type of extension you may face difficulty in scanning the QR code. Therefore, it becomes imperative to rule out this possibility.

If you are using any Chrome extension to change the theme, like the dark reader extension, you must disable it first. these extensions can sometimes change the background on which QR codes are displayed, as a result, your phone may not be able to scan the QR code properly.

You can try removing the extension one by one to see which extension was causing the issue.

12. Update Your Browser (Google Chrome)

An un-updated browser can also cause a problem, as WhatsApp needs to be updated all the time which you already know, as older versions of Whatsapp stops working after some time. Hence it also becomes imperative to update the Chrome browser or download the new one.

13. Use Another Browser

If you use only one browser on your PC and the problem is still there then you can try using another browser like Firefox, Microsoft Edge, Safari, etc.

14. Maybe the Problem could be with your WhatsApp account

If you have exhausted all the fixes described above then the problem may lie with your WhatsApp account rather than the mobile app or browser.

To know if the issue lies with your account only try your friend’s or family member’s WhatsApp app and scan the QR code from the same browser or machine which you are using. If it links up perfectly, the issue could be with your account. In that case, you can report the problem to Whatsapp. Follow the given below the steps to report the issue to WhatsApp:

1. Open Whatapp from the grid of icons.

2. Tap on the three dots in the top-right corner.

3. Now click on Help.

4. Now on the help page click on Contact us.

5. Write down your issue in detail and make sure you check the box for Include device information? (Optional)

6. Tap on Next and then hit Send my Question to WhatsApp Support.
